Answer:

D) 30

Step-by-step explanation:

3(a + 4b)-6 = 3 ( 4 + 4*2) - 6

                  = 3( 4+8 ) - 6

                  = 3*12 - 6

                  = 36 - 6 =30

What is the y-value for f(x) = cos(x) when x = 180°?<br> -1<br> 0<br> 1/2<br> 1
maksim [4K]
You start at 0 on the unit circle the cos of 0 =1, but at cos 0 there is no angle at all so there is no y value so at cos 0 y=0, 180 is the opposite direction of the starting point which is 0 so the x value of cos180= -1 but there is still no upward or downward angle ie.. y value. so the y value = 0 at 0 and 180. answer is 0

Jackson is two times older than Shelly. If the sum of their ages is 18, how old is Jackson?
salantis [7]
Answer: jackson is 12

explanation:
let the age be represented by x
jackson is 2 times older than shelly so
2x is jackson’s age and x is shelly’s age

since the sum of their ages is 18 then:
2x + x = 18

solve:
3x = 18 ➔ divide by 3 on both sides
x = 6

so now we know shelly is 6

jackson is 2 times older than her so:
2(6) = 12
